Second harmonic generation has been applied for a structural study of thin
epitaxial PbTiO3 films on a YBaCuO/SrTiO3 substrate. From the azimuthal ani
sotropic dependence the crystallographic orientation and the texturing para
meters an obtained with a high accuracy. (C) 1998 Published by Elsevier Sci
